An AsyncPublisherClient publishes messages similar to Google Pub/Sub, but must be used in an
async context. Any publish failures are unlikely to succeed if retried.
Must be used in an async with block or have aenter() awaited before use.
An AsyncSubscriberClient reads messages similar to Google Pub/Sub, but must be used in an
async context.
Any subscribe failures are unlikely to succeed if retried.
Must be used in an async with block or have aenter() awaited before use.
A location with respect to the message backlog. BEGINNING refers to the
location of the oldest retained message. END refers to the location past
all currently published messages, skipping the entire message backlog.
When this subscription should send messages to subscribers relative
to messages persistence in storage. For details, see Creating Lite
subscriptions <https://cloud.google.com/pubsub/lite/docs/subscriptions#creating_lite_subscriptions>__.
This message has oneof_ fields (mutually exclusive fields).
For each oneof, at most one member field can be set at the same time.
Setting any member of the oneof automatically clears all other
members.
